Rain Therapeutics Presents Preclinical Data on Lead Candidate Tarloxotinib at the American Association for Cancer Research (AACR) Annual Meeting

April 3, 2019

NEWARK, Calif., April 3, 2019 — Rain Therapeutics Inc., a privately-held, clinical stage biotechnology company focused on biomarker-driven, small molecule therapeutics for patients with cancer, today announced new preclinical data on tarloxotinib (Tarlox) presented at the American Association for Cancer Research (AACR) Annual Meeting 2019, held in Atlanta, Georgia from March 29-April 3, 2019. Three poster presentations detailed: 1) potent in vitro activity of Tarlox in a variety of EGFR and HER2 mutations, 2) data demonstrating that STEAP4 expression may serve as an additional biomarker to predict sensitivity to Tarlox in clinical trials, and 3) results of a comprehensive set of studies revealing the potential for Tarlox in treating NRG1 altered cancers.   

Key findings from Rain presentations include: 

  • Tarlox significantly inhibited tumor growth and regressed tumors in an NRG1 ovarian cancer patient-derived xenograft model (100% reduction in tumor size in the group dosed with 48 mg/kg of Tarlox as compared to a 150% increase in tumor size in the control group). 
  • Tarlox inhibits proliferation of EGFR and HER2 Exon 20 insertion mutations and osimertinib-resistant mutations in vitro, demonstrating potent activity and potential to treat EGFR-driven cancers that have been unresponsive to the current standard of care.
  • High STEAP4 expression is detected in EGFR mutant (del19, L858R and exon 20 insertion) lung cancer FFPE samples, and STEAP4 gene expression levels are significantly increased in EGFR-mutant non-small cell lung cancer samples as compared to wild type (p <0.05 in three cohorts of lung cancer datasets)

“Taken together, these exciting results provide strong evidence for the broad potential of Tarlox as a targeted cancer therapy,” said Avanish Vellanki, chief executive officer of Rain Therapeutics. “These data are encouraging as we continue our Phase 2 clinical trial of Tarlox in non-small cell lung cancer with EGFR exon 20 insertion and HER2 activating mutations, and we are looking forward to continuing to advance Tarlox through clinical development.”

Rain Therapeutics Presents Preclinical Activity of Tarloxotinib in NRG1 Fusion Cancers at the Annual American Association for Cancer Research (AACR) Meeting

April 2, 2019

Data support expanding clinical development of tarloxotinib to patients with NRG1 fusion and rearranged cancers with a tumor agnostic, basket strategy

NEWARK, Calif., April 2, 2019 — Rain Therapeutics Inc., a privately-held, clinical stage biotechnology company focused on biomarker-driven, small molecule therapeutics for patients with cancer, today announced that it presented new preclinical data on tarloxotinib (Tarlox), a hypoxia-activated pan-HER inhibitor, in NRG1 fusion positive cancers at the American Association for Cancer Research (AACR) Annual Meeting 2019, held in Atlanta, Georgia from March 29-April 3, 2019. These data support a potential addititional indication for Rain. Rain is currently conducting a Phase 2 clinical trial of Tarlox in EGFR Exon 20 and HER2 mutation positive non-small cell lung cancer.

“The activity observed by Tarlox in NRG1 fusion models is very exciting,” said Avanish Vellanki, chief executive officer of Rain Therapeutics. “The potency of tarlox observed across various in vitro and patient-derived animal studies was intuitive as NRG1 tumors rely on HER-signaling.”

Robert Doebele, MD, PhD, acting chief science officer of Rain Therapeutics continued, “NRG1 fusion positive cancers resemble NTRK fusion tumors in their addiction to a single oncogenic driver and their presence across multiple tumor types. Like EGFR and HER2 exon 20 insertion mutations, NRG1 fusions represent cancers that are difficult to drug without significant toxicity, hence providing another opportunity for the hypoxia-activated strategy of tarloxotinib.”  

NRG1 encodes the HER3 ligand neuregulin 1. NRG1 gene fusions are oncogenic drivers that overexpress the HER3 ligand, leading to heterodimerization of HER2/HER3 and activation of downstream ERK, PI3K–AKT and NF-kB pathways. NRG1 fusions are particularly enriched in invasive mucinous adenocarcinoma of the lung where they are found in 27-31% of cases and have also been reported in other cancer types with an overall incidence of 0.2% across all solid tumors. The preclinical studies presented at AACR demonstrate, among other significant findings, that Tarlox significantly inhibited tumor growth and regressed tumors in an NRG1 ovarian cancer patient-derived xenograft model. There was a 100% reduction in tumor size in the group dosed with 48 mg/kg of Tarlox as compared to a 150% increase in tumor size in the control group.

Data from the preclinical study were presented in a poster entitled “Tarloxotinib Exhibits Potent Activity in NRG1 Gene Fusion Positive Cancers.” A copy of the presentation materials can be accessed by visiting the Publications section of the Rain website.

Rain Therapeutics Announces First Patient Dosed in Phase 2 Trial of Tarloxotinib for the Treatment of Non-Small-Cell Lung Cancer with EGFR Exon 20 Insertion or HER2-Activating Mutations

March 19, 2019

First patient dosing comes within ten months of the Series A financing

NEWARK, Calif., March 19, 2019 — Rain Therapeutics Inc., a privately-held, clinical stage biotechnology company focused on biomarker-driven, small molecule therapeutics for patients with cancer, today announced that it has dosed the first patient in its Phase 2 clinical trial of tarloxotinib (Tarlox).  The start of the Phase 2 trial comes within 10 months of the Company announcing its Series A financing.

The open-label RAIN-701 study will evaluate the objective response to Tarlox in lung cancer patients with EGFR Exon 20 insertion or HER2-activating mutations. Tarlox is a hypoxia-activated prodrug of a pan-HER inhibitor.

“The dosing of the first patient in our Phase 2 trial is an important milestone for Rain as we advance Tarlox through clinical development,” said Avanish Vellanki, chief executive officer of Rain Therapeutics. “We continue to be very excited about the opportunity for Tarlox in all HER-addicted tumors, especially in patients with limited treatment options.”

The RAIN-701 study is a Phase 2 open-label trial designed to evaluate the objective response rate of Tarlox administered once weekly by intravenous administration. The trial will enroll approximately 40 patients at sites across the U.S., Canada and Hong Kong who have been diagnosed with NSCLC confirmed to possess EGFR exon 20 insertion mutations or HER2-activating mutations.

“Lung cancer patients with HER-family exon 20 mutations are in great need of effective and tolerable treatment options,” said lead investigator, Stephen V. Liu, MD, associate professor of medicine at Georgetown Lombardi Comprehensive Cancer Center. “As part of our mission, we are committed to engaging in essential clinical research to develop additional therapies for these patients.”

Rain Therapeutics Closes $18 Million Series A Financing

May 21, 2018

FREMONT, Calif., May 21, 2018 — Rain Therapeutics Inc., a privately-held, clinical stage biotechnology company focused on biomarker-driven, small molecule therapeutics for patients with cancer, today announced the closing of a tranched Series A financing of $18.4 million. The financing was led by San Francisco-based, Biotechnology Value Fund (BVF) and followed by Perceptive Advisors, Auckland UniServices Limited’s Inventors Fund and other private investors. BVF’s Gorjan Hrustanovic, Ph.D., will join the Rain Board of Directors in conjunction with the financing. The Series A round follows a $1 million convertible note financing completed in late-2017.

Rain plans to use the proceeds to advance the clinical development of its lead program, Tarloxotinib (Tarlox), in patients with EGFR and ErbB Exon 20 insertion mutations in non-small cell lung cancer (NSCLC). The company intends to commence a Phase 2 study in patients with EGFR and ErbB Exon 20 insertion mutations in NSCLC in the first half of 2019.

“With the proceeds from recent financings we can complete a Phase 2, proof-of-concept study and continue to advance Tarloxotinib,” said Avanish Vellanki, Rain’s co-founder and chief executive officer. “Our goal is to provide Exon 20 patients with a novel treatment option that results in strong anti-tumor responses while avoiding the debilitating, dose-limiting EGFR toxicities in the gut and skin that are associated with conventional small molecule inhibitors.”

“Targeting wildtype EGFR, or wildtype EGFR-like tumors has always been very challenging with conventional small molecule inhibitors because of the abundance of EGFR in healthy tissues,” said Robert Doebele, M.D., Ph.D., co-founder of Rain Therapeutics, and associate professor of medicine and director of the Thoracic Oncology Research Initiative at the University of Colorado.  “Patients with Exon 20 lung cancer show an addiction to EGFR, however the resemblance of EGFR Exon 20 to EGFR wildtype suggests most conventional strategies will be limited by toxicity. With its novel mechanism of action, Tarlox has the potential to address this inherent, unmet challenge in Exon 20 patients.”

Rain has worldwide development and commercialization rights for Tarlox through an exclusive license to technology developed at the University of Auckland.
